The GE Microprocessor Board DS3800HMPK1C1D is designed for quick installation in the drive. The board features a modular connector on 1 end and retention levers on the other end. The GE Microprocessor Board DS3800HMPK1C1D also is populated with 3 red indicator LEDs and 1 amber LED which are visible from the front of the board. The board also is populated with a microprocessor, erasable programmable read-only memory (EPROM) modules, and a 34-pin connector. It also is populated with 2 50-pin connectors.
When the amber indicator LED is lit, it means that the board is experiencing a warning condition. It also means that power is still applied to the board. It is best practice to resolve the issue when possible to restore function to the drive and the board. The first step to resolving the situation is to restart the board. It might be that interference has caused the command signals to be out of sequence or jumbled. A restart button is located on the board near the 34-pin connector. It is for use by a qualified servicer only due to the possibility of a high-voltage electric shock if components are touched while power is present in the board.
The restart button temporarily stops processing on the board without shutting off power. After a number of seconds, processing is automatically restarted without user intervention. Carefully press the button without touching other components. If the problem is resolved, the amber LED will cease to be lit and normal processing will resume.
